Passive Smoking & Children : Clinical & Experimental Forums. International Academic Symposium. Essen, DEU, 1998/08/25.
1 We aimed to study whether passive smoking is associated with respiratory ill health in primary school children in Hong Kong. 2 In this cross-sectional study, a standardised structured questionnaire was used to obtain information on respiratory symptoms, smokers in the household and smoking habit of the children.
A random sample of 30 primary schools was included.
Four classes were randomly selected for each school, one class each from each school year of primary 3-6.
A total of 3964 children aged 8 - 13 years completed the questionnaire during October 1995-May 1996.
The response rate was over 94%. 3 In 3480 children who had never smoked, after adjusting for gender, age, place of birth and living district, the odds ratios (95% confidence interval) were :
(a) throat problems, 1.35 (1.08-1.68) ;
(b) cough, 1.54 (1.28-1.84) ;
(c) phlegm, 1.43 (1.21-1.70) ;
(d) wheezing, 1.21 (0.89-1.41) ;
(e) nose problems, 1.17 (1.021.35).
The odds ratios increased with increasing number of smokers at home (P for trend<0.001 ; except for wheezing, P=0.3).
The odds ratios for having any of the above symptoms for one, two and three smokers at home were respectively 1.15 (0.99-1.34), 1.48 (1.16-1.88) and 2.03 (1.47 - 2.81) ; P for trend<0.001. 4 We conclude that the results provide further evidence that passive smoking is a cause of respiratory ill health in school children in Hong Kong.
